Description and Uses

Met-enkephalin analog found in opioid extracts of brain and adrenal chromaffin cells that is an artifact generated by trichloroacetic acid extraction. MUS is used as a fluorimetric substrate for arylsulphatase enzyme. Subsitution of the hydroxyl group of 4-Methylumbelliferyl sulfate potassium salt causes the excitation wavelength of the umbelliferone to shift to shorter values and also brings about a decrease in fluorescence. Fluorescence: max. Abs = 334 mm; max. Em. = 370 mm
